CHENNAI: DMK deputy general secretary Kanimozhi Rajathi Karunanidhi on Monday criticised the TVK govt in Tamil Nadu over allegations that ruling party MLA Arul Vignesh had harassed Kallakurichi district collector by sending her obscene messages and visiting her residence in an inebriated state.In a post on X, Kanimozhi said reports were circulating on social media that a personal security officer (PSO) had been assigned to the collector following the alleged incident.“Under the incompetent TVK administration, law and order has collapsed, with a series of murders and robberies. Now, even a district collector is said to be facing a security threat from a TVK MLA,” she said.Wondering whether assigning a PSO would address the issue, Kanimozhi asked what protection the chief secretary could provide to the collector through such an arrangement.She sought a response from chief minister C Joseph Vijay on the allegations.
